Some data loads in my application are depending on being strongly consitent, others are not.
In https://developers.google.com/appengine/docs/java/datastore/queries#Java_Ancestor_queries I read: Setting an ancestor filter<https://developers.google.com/appengine/docs/java/datastore/queries#Java_Ancestor_filters> allows for strongly consistent queries. Queries without an ancestor filter only return eventually consistent results. Lets say I have a class MyClass.class { @Parent Key parent; @Index Key anotherParent; @Index String firstName; } Question 1: Does this mean that queries with both ancestor limiter and filters are strongly consistent? Example: ofy().load().type(MyClass.class).ancestor(parentKey).filter("firstName = ",firstName); Question 2: In some other data loads, performance is more important. Assume example "A" and "B". Will "A" have the same performance as "B"? A. ofy().consistency(Consistency.EVENTUAL).load().type(MyClass.class).ancestor(parentKey).filter("firstName = ",firstName) B. ofy().load().type(MyClass.class).filter(anotherParentKey).filter("firstName = ",firstName) Thank you in advance -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
